How many atoms are in a sample of 2.39 moles of neon (Ne) atoms?

6.02 * 1023 atoms Ne

1.44 * 1024 atoms Ne

3.97 * 10-24 atoms Ne

2.52 * 1023 atoms Ne

Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles.

2.39 moles Ne (6.022 x 10^23 atoms / mole) = 1.44 * 10^24 atoms Ne
